英文摘要a novel cathode material for lithium-ion batteries, carbon-coated li3v2(po4)(3) particles which anchored onto graphene sheets (li3v2(po4)(3)@c/graphene) have been prepared by a modified pechini method. it is first proposed that the graphene oxide can act as a chelating agent in the reaction process. the nanocomposite is characterized by x-ray diffraction (xrd), scanning electron microscope (sem), transmission electron microscopy (tem) and element analysis. the composite shows excellent c-rate performance, delivered capacities of 104,91 and 85 mah g(-1) at 5,30 and 50 c in the voltage range of 3.0-4.3 v. respectively. moreover, the cycling performance is also improved in higher voltage range of 3.0-4.8 v. the capacity retention is 83% with the capacity of 131 mah g(-1) at 10 c after 100 cycles. the outstanding features are desirable and enable the material to be an excellent cathode for lithium-ion batteries.
